To @ZZ whom, t may concern:

Beit known that we, FREDERICK J VAN OrsE and VILLIAM O. VAN OISE, citizens of the United States, and residents of Mayville in the county of Chautauqua and State of New York, have invented anew and useful Mattress-Frame, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

The invention relates to frames for wovenwire mattresses; and the object of our improvement is to providea light and rigid metallic frame which will not warp or torsion. This purpose is accomplished by making the side and end rails of sheet metal, with fianges thereonand a corner-block which connects and locks the side and end rails by the use of one bolt at each corner in a manner hereinafter described.

In the drawings, Figure 1` is a plan view of one end of a lwoven-wire mattress having our improvements. Fig. 2 is an end elevation of one corner of the mattress-frame, showing the construction of o ur side rail and corner-block. Fig. 3 is an end elevation of a modification of our side rail and corner-bolt. Fig. 4 is aside elevation of a corner of our mattress-frame. Fig. 5 is a plan view of corner-block.

Similar numerals refer to corresponding parts in the several views.

rlhe numeral 1 is the fabric, which is usu ally made of woven wire. The frame is composed of a side rail 2, which is made of two pieces of sheet metal. The lower piece 3 is made in a V shape, with a cylindrical lower side 4, whichI gives great strength to the bottom of the rail. The upper edges of piece 3 are turned outward in flanges' 5. The cappiece 8 extends straight across the upper part of the V a little below the top and is shaped so as to correspond with theangle of the V, as at 7 7, and then turned out horizontallyY at each side and is turned down over flanges 5, thereby completing the two flanges 6 6 at the upper corners of the rail. Y

It is apparent that the straight central part of' cap-piece 8, in combination with the angles 7 7, forms a brace or lock which prevents the withdrawal of side fianges 5 from the turned edges of the cap-piecel 8. On account of this brace it is usually only necessary to insert a rivet 9 at each end of fianges 6 to hold the parts in place and prevent torsion of the rail.

A moditication of the cap-piece 8 is shown in Fig. 3 in the inner V 10, which would serve a good purpose, but does not brace as squarely across the V-shaped Linder piece 3, or piece 8 may extend straight across the top of the rail, as shown at dotted line 11 in Fig. 3, and make a strong rail; but it cannot brace and lock the corner, vas hereinafter described,

and therefore the form shown in Fig. 2 is preferred.

Our `corner-block 12 is made on its lower side with rabbeted edges 13, which fit the angles 7 of piece 8 and the tops 14 of the flanges 6. Block 12 is made of sufficient length that the tongue formed by the rabbeted edges may have a strong hold in the groove in the upper side of side rail 2. It is extended out beyond the end of the rail for some distance and rounded, as at 15, for convenience indrawing the end of the mattress along the floor-as, for instance, when the furniture-dealer draws the mattress from thc rack to show the same. Orosswise in the upper side ofl block 12 is the cut 16, whose use will f of the end rail 18 to "giveadded strength and" stiffness for clamping the fabric thereon. Rail 18 is placed upon its side upon the two corner-blocks l2 at one end and with a flange 6 in crosscuts 16 in the two blocks. Orosscut 16 is made with just sufiicicnt width to receive flange 6 on the lower side of the end rails, and it is apparent that each end of the end rail 18 will thus be held as in amortise at right angles to the side rails 2, and that the two corner-blocks at each end of the frame will assist each other in locking the rail.

The entire corner is held in place by cornerbolt 19, which extends up through the end of side rail 2, through corner-block 12 andend rail 18, and it is obvious that when the corner
